End-to-end encryption (E2EE)

Zoom have enabled end-to-end encryption for meetings but it is not enabled by default and has to be applied by individuals prior to starting a meeting, providing additional protection when needed.

Considerations before enabling E2EE

End-to-end encryption may not be suitable for teaching using Zoom because, when enabled, end-to-end encryption will disable the following features:

*As of version 5.5.0 for desktop, mobile, and Zoom Rooms, these features are supported in E2EE meetings.

If you require any of the above features you can disable encryption by following the above instructions and turning off the option to Allow use of end-to-end encryption for your account.

Enabling end to end encryption for meetings requires all meeting participants to join from the Zoom desktop client, mobile app, or Zoom Rooms. But anyone who doesn’t have the application will be prompted to download it when attempting to join the link.

Users will not be able to join by telephone, SIP/H.323 devices, on-premise configurations, or Lync/Skype clients, as these endpoints cannot be encrypted end to end.

Zoom web client and third-party clients leveraging the Zoom SDK are also not supported at launch.

Enabling end-to-end encryption

Enabling Encryption is done in the Security settings for your account on https://universityofleeds.zoom.us/meeting#/

Select Option two - End-to-end encryption and press save to apply E2EE encryption globally to your account and make all upcoming meetings encrypted.

Selecting Option two to enable E2EE



If a meeting is unsecured then anyone can join a Zoom meeting if they know the meeting link. Links shared via unsecure or publicly viewable sharing sites such as Twitter, Facebook or other social media platforms expose the meeting to uninvited guests. This is known as 'Zoombombing'.
If you ensure you have set-up your meeting/s following the information above, including joining via the University’s site licence universityofleeds.zoom.us using Single Sign On (SSO), then your meeting/s should not be subjected to Zoombombing
